The field of sensory features in children with Autistic Spectrum Disorder (ASD) is
being relatively recently explored and trained, and it is considered a crucial intervention
during the stage of early childhood education, because it can interferenciate with other
learning processes. However, in Spain there are few materials to evaluate this field in
pre-school children, and none of them is validated with Spanish sample. In the present
paper, two studies were designed: firstly, a sensory test was created to better assess the
sensory experience in a comprehensive way, both with typically developing and ASD
children, with ages ranging from 3 to 5 years-old. This sensory test was named “Test de
Sensorialidad para Educación Infantil”, TSEI). In this first study groups of children
with typical development of different ages were compared, and it was found that
sensory difficulties were more common in younger children. In the second study, the
TSEI test was used to compare children with ASD to children with typical development,
and also as a pre and post test measure to test its usefulness to establish the baseline of a
intervention design. Thus, it was observed that children with ASD showed greater
sensory features in almost all areas, compared to children with typical development. In
addition, it was found those children with ASD who had received an individualized
intervention, improved they sensory features in comparison to the group of children
with ASD who not received that intervention. And, the TSEI allowed collecting the
evidence of this improvement. Conclusions about the usefulness of the TSEI to measue
the sensory experience in this range of age are commented, as well as the effectiveness
of designing individualized methods for training the sensory features with the help of
this measure.
